MV1-B-64-620-1-A12-B-C Description

Short technical summary and product information.

The Littelfuse MV1-B-64-620-1-A12-B-C is a single-pole magnetic circuit breaker with hydraulic delay. It is rated for 20A continuous current at 250V AC/DC. The breaker uses a magnetic (hydraulic delay) mechanism for overcurrent protection, providing time-delayed tripping characteristics.

This circuit breaker features a push-pull actuator for manual reset and is designed for panel mount snap-in installation. It has no illumination. The breaker is approved by CCC, CSA, and UL1077.

The hydraulic delay design allows the breaker to withstand temporary inrush currents without nuisance tripping, making it suitable for applications with motors or transformers. The panel mount snap-in mounting simplifies installation in control panels and equipment enclosures.
